2 Claims.

The object of my invention is to improve an oil burner. This application discloses an improvement on my Patent No. 1,857,846, dated May 10, 1932 for Oil burners.

In the conventional type burner, now in use, a considerable time interval is necessary between the lighting of the burner and its successful functioning. Furthermore, when the conventional burners operates, it produces carbon, which, when entrained in air, forms smoke. This is particularly true in the burning oi heavy oils of low volatility.

Among the specific objects of my invention, one is to obviate these defects. More specifically, my device comprises means for initially burning the more volatile portions of the oil and utilizing the heat of combustion, thus obtained for subsequently igniting and burning the heavier portions of the oil.

By the process, herein described, the fuel oil is forced upwardly through a vertical pipe and then permitted to overflow and fall on a mutilated washer and to fall from this washer on to a lower washer in spaced relationship with the upper washer, and then downwardly upon successive All of the washers are covered with a single cap, which is supported on the upper washer. The mutilated edge oi each washer is staggered relative the mutilated edge of each subsequent lower washer. By these means, the flow of oil is staggered from each Washer to each successive lower washer. When the oil is passed over the lower washer, it falls on a perforate disc, which is substantially larger enveloping the Washers. That portion of the oil, which has not been volatilized by this time, then passes through the perforations in the perforate disc and falls on to a second imperforate disc below the perforate disc and in spaced relationship therewith. Both the perforate and imperiorate discs are positioned concentrically and secured to the vertical fuel supply pipe. By these means the more volatile portions of the oil are burned and the resulting heat of combustion obtained is utilized for subsequently igniting and burning the heavier portions oi the oil.

With these and other objects in View, my invention has relation to certain novel features of construction and arrangement of parts, as will be hereinafter more fully described, pointed out in the claims and illustrated in the drawing, in which Fig. 1 is a plan View of the conventional oil burner with my improvement shown.

Fig. 2 is a iront elevation of the structure shown in Fig. 1.

Fig. 3 is an enlarged iragmental sectional elevation of my improved addition to the burner, showing the periorate and imperforate discs fragmentally.

Fig. 4 is a sectional plan View on the line 4-4 of Fig. 3, showing the shapes of the washers used in my attachment.

Numeral 5 indicates a cast cylindrical cup, having the tapped hole 6 in its center and the peripheral flange 7. The supply pipe 8 is in threaded engagement in the tapped hole 6. Numeral 9 designates a perforated sleeve, having the perforaticns 10. Numeral `11 designates Ya cylindrical cap having the top 12 and depending flange 13. In the cylindrical cap 11 is formed a central opening vco-axial with thev supply pipe 8. Numerals 14 designate rods passing through perforations in the top 12 and through holes in ears 15, which are formed integral with the cast cylindrical cup 5. There are a plurality of such rods 14. By means of nuts 16, the perforated sleeve 9 and the cylindrical cap 11 and the cast cylindrical cup 5 are secured in irictional engagement.

On the supply pipe 8, in spaced relationship with the bottom oi the cast cylindrical cup 5 is secured the imperiorate disc 17. There is no iluid communication between the supply pipe 8 and the imperforate disc 17. The open end of the supply pipe 8 terminates slightly above the bottom of the perorate disc 18. Thus far, the device is the same as in my former Patent No. 1,857,846. The improvement for which I desire to secure a patent in this application is the following:

The upper end of the supply pipe 8 is internally threaded. Numeral 19 designates a nipple, which is in threaded engagement with the upper end of the supply pipe 8. Numeral 20 designates a pipe secured to the nipple 19. Numeral 21 designates a mutilated washer secured to the upper end of the pipe 20. The mutilated washer 21 is circular with the exception that a portion has been removed, making the plan view of the washer that shown in Fig. 4.

Numeral 22 designates a second mutilated washer of the same shape as mutilated washer 21 and secured to the pipe 2O in spaced relationship with washer 21 and so positioned that the mutilated portion of washer 22 is at the opposite side of the pipe 20 from the mutilated portion of wash- Numeral 23 designates a third mutilated washer of the same size and shape as washers 21 and 22, in spaced relationship with mutilated washer 22 and positioned the same as mutilated washer 21.

Numeral 24 designates a fourth mutilated Washer in spaced relationship with mutilated washer 23 and positioned as mutilated washer 22. In this way, additional washers are positioned on the pipe 20. In Fig. 3, 7 such washers are shown. Numeral 25 designates a cap, which is circular in cross section, as shown in Fig. 4 and whose inner radius is equal to the normal radius of the mutilated washers 2l to 24 inclusive. All of the mutilated washers are of the same size and preferably positioned equi-distant from each other. The cap 25 when positioned over the pipe 20 is supported on one side by the normal portion of the mutilated washer 21 and on the other by the normal portion of the mutilated washer 22. Each mutilated washer is in contact with the inner surface of the cap 25 on one side, but not on the opposite side. The cap 25 is of such length as to slightly envelope the nipple 19, but not to extend to the perforate disc 18. It is of such diameter as to leave an annular space between its inner wall and the outer wall of the nipple 19. The passage of oil and vapor is shown in Figs. 2 and 3 by arrows. The oil is forced upwardly through the supply pipe 8 through the nipple 19, through the pipe 20 and onto the upper surface of the mutilated washer 21 and flows downwardly over the mutilated edge of the washer 2l between the mutilated washer 2l and the inner surface of the cap 25. It then falls onto the mutilated washer 22 and is forced to travel gravitationally to the opposite side of the mutilated washer 22 and falls over the mutilated edge of the mutilated washer 22 onto the mutilated washer 23. After having passed over all of the mutilated washers, the oil that has not, as yet, been vaporized, or has not been vaporized, falls onto the perforated disc where the process of vaporization and burning continues. Any of the heavy oil, which has not, as yet, been vaporized and burned or vaporized in its travel, falls through the perally, it is known that the heavier more volatile portions of the oil require more heat to produce their volatilization and burning. By the device herein described, the lightest most volatile oil is vaporized on the upper mutilated washers, such as 21 and 22. Therefore, the greater the travel of the oil over the mutilated washers, such as 21 to 24, the greater the heat that is applied to the oil, and the greater the certainty of volatilization and burning within the confines of the cap 25. Only the heaviest and most non-volatile portions of the oil reach the perforate disc 18. By radiation through the cap 25, the entire space within the perforated sleeve 9 is heated, so the additional and nal volatilization and burning takes place, either on the perforate disc 18 or the imperforate disc 17.

What I claim is:

l. In an oil burner, a vaporizer comprising in combination an oil supply pipe, imperforate horizontal mutilated washers iiat on their upper sides secured exteriorally to said supply pipe in spaced relationship with each other, and below the discharge end of said oil supply pipe, and a cap secured in frictional engagement over said washers.

2. In an oil burner, a vaporizer comprising in combination an oil supply pipe, imperforate horizontal mutilated washers flat on their upper sides secured exteriorally to said supply pipe in spaced relationship with each other, and below the discharge end of said oil supply pipe, the mutilated portions or" said mutilated washers being staggered, and a cap in frictional engagement with each alternate washer in one portion of the cap and each other alternate washer on the remaining portion.
